How can cement be carbon-neutral?

German building materials company HeidelbergCement has announced it will upgrade one of its factories to make it the world’s first carbon-neutral cement plant.
A carbon capture facility will be built next to the existing cement plant on the Swedish island of Gotland – by 2030 it will be able to capture its total carbon dioxide emissions, an estimated 1.8 million tonnes of carbon dioxide.
The company says the captured carbon dioxide will be transported to a permanent offshore storage
